The main reason and the sine qua non for accounting for postdural puncture headache (PDPH) is an excessive loss of cerebrospinal fluid (CSF) from the subarachnoid space after the puncture of both dura mater and arachnoid
After perforation of the dura mater, the initial liquid outflow was highly variable between dura mater specimens (3.7 ± 5.0 [SD] mL/10 min, median 2.2 mL/10 min; minimum 0 mL/10 min, maximum 18 mL/10 min, n = 17; using a 27-gauge Quincke needle), even when different fragments of the same cadaver donor were tested (e.g. 0 mL/10 min, 2.5 mL/10 min, 6.2 mL/10 min and 14 mL/10 min of liquid outflow from each of the 4 distinct tested dural fragments, respectively; 52-year-old female)
